Helmig's resignation prompted a state investigation by the Kentucky Retirement System into possible "double-dipping" issues, according to a 2015 Enquirer story. The practice of double-dipping is when a person opts to collect a pension and then returns to work to collect a paycheck.

Maydak did not immediately respond to requests for comment about whether the resignation was pension-related.

Helmig, a Republican, is the only sheriff candidate on the upcoming Nov. 6 election ballot.
